Overview
The DG401CY is a dual, high-speed analog switch from the DG401/DG403/DG405 series, manufactured by Analog Devices Inc./Maxim Integrated. It features two single-pole/single-throw (SPST) normally open switches in a 16-pin Narrow SO package. The device operates on a single +10V to +30V supply or bipolar supplies of ±4.5V to ±20V. Key electrical parameters include a maximum drain-source on-resistance of 45Ω and an on-resistance match between channels of 2Ω max. Switching times are 150ns max for turn-on and 100ns max for turn-off. The device guarantees low charge injection of 15pC max and off-leakage current less than 5nA at +85°C.
Feature Summary
- Dual SPST configuration with guaranteed low on-resistance matching between channels
- High-speed switching capability with low power consumption
- Rail-to-rail signal handling over specified supply ranges
- TTL/CMOS logic compatible inputs
Applications
- Sample-and-Hold Circuits
- Test Equipment
- Guidance and Control Systems
- Audio Signal Routing
- Battery-Operated Systems
Procurement Notes
Verify the specific suffix 'CY' corresponds to the 16-pin Narrow SO package and the 0°C to +70°C operating temperature range as defined in the official ordering information. Confirm that the component meets the required environmental specifications for the intended application environment before finalizing procurement.
Selection Notes
Select the DG401CY when a dual SPST switch configuration is required within the commercial temperature range. Ensure the application voltage does not exceed the absolute maximum ratings of 44V between V+ and V-. Consider the 45Ω maximum on-resistance and 150ns switching time against system performance requirements.
Part Context
The DG401CY belongs to the redesigned DG401/DG403/DG405 family of improved dual high-speed analog switches. This family offers enhanced performance characteristics compared to previous iterations, including lower on-resistance flatness and reduced charge injection. The DG401 variant specifically provides two independent SPST switches.
Replacement Considerations
Direct replacement options within the same package and specification profile include the DG401DY for extended temperature ranges (-40°C to +85°C). Other variants in the series such as DG403 or DG405 offer different switch configurations (SPDT or DPST) and should be evaluated based on circuit topology requirements.
